Drive sprocket spring, MB
MBL0492This spring is part of the front sprocket set-up and is used to grip the sprocket in place.
Genuine springs can go weak over time and the sprocket can slip.
Early Series 1 springs are shorter and do not work well in modern motors, it's always worth fitting a new spring on a rebuild or a chain/sprocket change.
Another part made for MB after we were so disappointed with supplies from other sources.
